Steamer

Abstract

An improved steamer for heating food includes a base with a heating unit and a controlling switch, a plurality of pot units, a plurality of racks, and a lid. The pot units seat on top of the base, and the racks are placed on a bottom of each pot unit. Several steam ducts are arranged on ends of the pot units, and an opening is defined in the steam ducts. A cover is put on the opening. The lid is placed onto the upper pot unit. When the steamer with food is heated, the steam from the heating unit is introduced into the pot units from the openings of the steam ducts to heat the food. Each pot unit is isolated, and the steam introduced will not mix, and odors from the pot units will not interfere with other pot units.

Description

BACKGROUND OF THE INVENTION[0001]1. Technical Field[0002]The prevent invention provides an improvement to a steamer and, more particularly, to an improved steamer in which each of stacked pot units is supplied with steam via an individual steam duct to homogeneously and individually heat up food in the individual pot unit, thereby preventing the steam from becoming extensively built-up merely in the lowest level and properly and individually directing the steam to each level of the pot unit to heat up the food to the intended temperature. In addition, mixing of odors from different food in different pot units can be also prevented.[0003]2. Description of Prior Art[0004]Conventionally, there are a variety of steamers in shape as well as configuration. Typically, three or four levels of pot units made from aluminum material are stacked together to configure the steamer. In general, the bottom of each pot unit is defined with a plurality of ventilation holes, and a vessel or container ...

AI Technical Summary

Benefits of technology

[0007]The present invention provides an improvement to overcome the problems encountered by the existing steamer. It is intended to direct the steam into each of the stacked pot units individually at each level to homogeneously heat the food placed thereof to effectively prevent a steam built-up merely at the lowest level. Accordingly, the food placed in each level is heated by the steam introduced therein periodically, to have the food heated to its intended temperature. In addition, since the pot units are isolated from each other, mixing of the odors from different food can be effectively avoided.

[0008]It is a primary objective of the present invention to provide an improved steamer which is configured with a base built-up with a heating unit and a controlling switch, a plurality of pot units, a plurality of racks, and a lid. The pot unit can be readily seated on top of the base, and the racks can be readily placed on a bottom of the pot unit. At least one or more than one steam ducts are arranged on longitudinal ends of the pot unit. At least one opening is defined in the steam ducts at each end, and a cover is associated with each opening. The steam from the base can be readily introduced into each pot unit through the openings. The lid is placed onto the upper pot unit. Once the steamer is filled with food to be heated, the heating unit within the base can be turned on, and the steam can be introduced individually into each of the pot units from the opposite openings of the steam ducts to evenly heat the food placed in each of the pot unit. Since each of the pot units is isolated from each other, and the steam introduced therein is also individual without mixing. Accordingly, odors of food from different pot units will not interfere with the food located at other pot units.

[0012]According to a fifth purpose of the present invention, each pot unit is provided with tabs on opposite sides thereof for readily seating onto another pot unit and for convenient handling by the user.

[0014]According to a seventh purpose of the present invention, the openings on opposite sides of each of the pot units seated onto the base have been offset from each other, such that the steam from the base can be introduced diagonally to evenly heat the food placed in the pot unit.

[0015]According to an eighth purpose of the present invention, the rack placed within the pot unit can be readily removed and replaced with a hollowed rack, and the ring of the hollowed rack can be readily disposed within the grooved shoulder to accommodate elongated food.

[0016]According to a ninth objective of the present invention, an improved steamer, which is configured with an improved steamer for heating a plurality of food with steam, comprises a base built-up with a heating unit and a controlling switch, a plurality of pot units, a plurality of racks, and a lid. The pot unit can be readily seated on a top of the base, and the racks can be readily placed on a bottom of the pot unit. At least one or more than one steam ducts are arranged on a longitudinal side of the pot unit. At least one opening is defined in the steam ducts located at the longitudinal side. The steam from the base can be readily introduced into each pot unit through the opening, and the lid is placed onto the upper pot unit. Once the steamer is filled with food to be heated, the heating unit within the base can be turned on, and the steam can be introduced individually into each of the pot units from the opening of the steam ducts located on the longitudinal side to evenly heat the food placed in each pot unit. Since the pot units are isolated from each other, and since the steam introduced therein is also individual without mixing, odors of food from different pot units will not interfere with the food located at other pot units.

Problems solved by technology

However, the food placed in the lowest level can be easily overheated or socked by the steam, rendering a poor appearance or setting of the food.
